HENR HAsENBuR6m HARV YWILEYCORBETT Patented Sept. 14, 1943 'Thisinventionrelates generally to weather stripping materials and isparticularly directed} to sheet metal'we'ather strip means for useon 7windows of the type havingltwdormoresash mounted "for movement in a;frame. I leretofore, some forms of weather stripping for this 7' type ofwindow included plates or strips whichwere'po sitionedbetweeritheslidable sash and the walls of guideways formed-ins'aid frame. Thesestrips were provided 'withribs which extended-into channelsformed in thesashjthe obje'ct being the provision of tortuous passages which wouldpre- V clude'theentranc e of the elements'into the buildmg. I This typeof weather strip is objectionable because the. eeenmuse fit ratherti'ghtly'in the. gui d'eway to prevent air flowfand upon becoming idamp, will swell and bind,- sometimes becoming immovable. y

One of the'objects of the present invention resides in the provision ofweather strippingineans withweather stripineans-form'ed in accordan e swith the present invention, the plane of the" sec;

tion being-taken through the upper's'ash; I Fig. 2 is a vertical'sectionalview taken through the sash shown in'FigfLthe plane ofthis''sectiori being indicated by the line II-Il of Fig. 1;

This member'includes a side-rail 2 and inn'er' ahd outerstripes; The latter men'ia bersr -proiectslightly beyond the outer'f'ace ortn ,rail '2 to provid'e -guide walls 4 at. the'side aedges' ofthe rail; 7 These walls: cooperate with :the rail -to-form alongitudinally extending channel in the 1 frame-.

i Another object resides in- 'the provisioni of weather strip meanswhich may e removed and replaced without destruction of the variousparts and with a minimum ot-labor and inconvenience theouter facethereof is formed'with a longitudinally ektending groove ,5 for therec'epti0n of a parting-stripfi which forms a part ofthe weather stri'pmea'nsl The Strip 6 is" formed 'frorn sheet metal and includes a body 1provided by bending the material to produce an pfuter wa-ll 8- and apair of rearwardly directed 'side .wall '9; #Tl'iese f walls terminateat" theirouter edges-in laterally Y 'A further object rests" inft'he'forrnationof H means of the type mentioned which vincludes partingstripadapted tobe located betweenthe sash guides and provided withflexiblewalls-on' which are formed flange means, the sash being equippedwith complemental stripshaving slidable engagement with the-partingstrip; the sash strips being engaged with; both the -walls-and flangeswhereby-a doubleseal will-be produced; 7

Another object rests in-"the provision of a novel manner by'whichthe-sections of the, weather strip means are secured to the framefandseen; the parting .stripmembersn being loosely disposed in channels in''the'frame' and the sash strips directedsectio'ns H] which in'turn'terminate in flanges H directed toward the 'sa'sh |2 positioriedfor sliding movement in the channel forrned by the wallsf ta'nd therail- 2.

In the drawing: i

sash The side weueaer the partihg stripconverge toward the rail and;intermediate or their width, they are provided with longitudinally ex}'f orr'niia'rrow diverging-sec- "wh'ic illhe hereina er The flanges H7diverge slightly as} 15-11 Walls 9 to providerecesses forweather-stopstrips' l3 carried by the 'sash.- As illustrated in Figs.

- land 4, the stop strips include flat body portions I4 landlaterallydirected flange portions IS, the latter forming an obtuseangle with theformer. Toward the outer edge of the flange portion, the

edge i curledslightly back toward the plane occupied "by the bodyportion. This manner ofv bending the stop strips provides longitudinallyextending rounded corners for engagement with the parting strips, thestop strips being disposed within the spaces formed between the flangesl l and the side walls 9 of the parting strips. When 50 positioned, therounded corner formed between the sections and [5 of the stopstripsengages the diverging section of the side wall 9 and the outer roundedcorner engages the inner surface of the complemental flange H.

To hold these rounded corners in this engagement with the partingstrips, the parting strips are secured to the sash by forminglongitudinal 1 1y extending slots in the sash adjacent to their edges.

being formed in the inner side while the slot in the lower sash is onthe outer side. To retain These strips extend into thesash at an angleto the surfaces, the slotinthe upper Jsash the stop strips in theirpositions inthe' sa'sh,.

the body section of each stop strip has a per-.

forated lug I6 directed laterally from'on'end.

This lugoverhangs one end of .the, sashuan'd a screw; I-l' or othersuitablesecuring element projects through, the perforation in. theluginto the material of the sashtoqretain the stop-stripagainst-longitudinal movement relative to. the

sash.

After: the various parts have been assembled into-the positions shown inFig. 1', the stops-trips will have a double engagement-with the spfi'tingv stripto efiectively prevent i the entrance ofizairintothe-building between the-sash and the'frame.

If: the-sash should swell or shrink due to weather conditions," thestop, strips may moveg-intoaand out. of thei'spaces betweenthe-sidewallssa-nd flanges ofithe par-ting strip;without affept-ing; theability thereof to move longitudinallyoi theywindow frame; By formingthediverging sections in-the-w-a-lls 9, the stop strips willhave a greaterextent of engagement with the ,walls when-the sash moves laterallyintoand out of" the. guide groove.- The-divergin-g sectionsof thewalls9; also While the invention has been illustrated and described in but asingle form, it is obvious that minor changes may be made in the variousparts and their relation without departing from the spirit and scope ofthe invention as set forth in the following claims. Whatis-cl'aimed is:

1. Weather stripping means for windows having a frame and upper andlower sash mounted for movement in spaced parallel guides, partingstrip-means disposed in said frame between said sash'f'guides andextending the full length thereof, said parting strips having spacedflexible walls which; converge; outwardly from said sash, in-

termediate longitudinally extending portion of ifromqsaidsash andterminating indiverging flanges directed toward said sash; andweatherstop strip means projecting from. the opp sed faces; of said sash,saidstrip meansprojecting in-tothe space between the. wallsand flangesof serve to hold the :outer portions of the stopstrips I infirm-engagement theiflang-es l-l. r V v l Through the provision of'theslots inthe sash and the single perforated lug on each stopstrip,theqweather stripping can beinstalled on the windows with a minimum oftime-and effort. 'l he parting strip'is merely positioned in the withthe inner surfaces of groove-5, no securingelements beingrneces'sary'. 1

As but a single securing element isused for each stop strip and theseelements pass through a perforated lug from the'top and bottomv ends-ofthe sash, the strips maybe installed after-the window has-been assembledand secured intthe saidparting strip, andbeing curved to engage both thewalls and the flanges ofsaid parting strip.

3. Weather stripping for slidable window sash, a window framehavingguides in-which'a pair. of window sashes -are' mounted forverticalv slidin movement, said frame being formed on eachside thereofwith; a vertical groove located between said sashes,ametallicpartingstripadapted to occupy each of said grooves and coextensive in lengththerewith said parting-z strip providing a metal sheet formed to providea transversely ex tending outer wall, vinwardly directed side wallsandoutwardly and laterally bent flanges, the latter having bearingengagement with the wall surfaces of saidzgroove, the intermediateportions of-tl ie-side walls of said strip occupying,planes angularlydisposed with respect to those. of the continuing inner and outerportions ofsaid. ide walls, and metallic weather strips carried. by andextending the full height of each of said sashes, each of said stripsprojecting in. acute angular relationship from thevvertioal plane of thesash on which it is mounted and-having its free outer portiondeflected'angularly for resilient wiping engagement with both theangular intermediate portions of one of the sidewalls of, said partingstrip andthe adjacent side surface of one of said parting strip-flanges.
